    What are Power Transmission Belts?

    Power transmission belts help to drive the transmission by the transfer of power to different parts in the system. This system normally consists of a belt and at least two pulleys to transmit the motion needed, commonly used in the automotive industry.

    Types of Power Transmission Belts

    Power transmission belts come in various types and styles. Popular types include:

    V-belts - have tapered sides and a flat bottom with a trapezoidal cross-section. They work by using the friction between the belt and the pulley to transfer power and have a higher power transmission capacity than flat belts. V-belts are popular due to ease of installation, low cost and are available in a wide range of sizes.

    Synchronous belts - also known as timing belts, have a toothed profile and can be used as an alternative to chains and gears. They overcome belt slippage with teeth that engage with corresponding grooves in the pulley or sprocket boosting drive efficiency above a V-belt. They're used in high-powered transmission applications, such as water pumps, fuel injection pumps and camshafts. They are thin and flexible making them ideal for use where high speed or small pulleys are required. They are less noisy than chain drives and energy-efficient through the life of the belt.

    Flat belts - have a rectangular cross-section that provides a greater level of consistent friction between belts and pulleys. They have low creep and are efficient due to their low bending losses and energy-saving properties and are used in all areas of industrial areas using power transmission for their versatility.
